Freight Savings
For large heater orders over $10,000, freight savings are available by contacting our sales team at 1-888-281-9337.

Model HER Horizontal Delivery Heaters: Recommended for use in greenhouses or buildings where ceilings are low and with few obstructions. Units are equipped with air deflector blades that can be adjusted to lengthen or shorten heat throw as well as to direct heated air up or down. Units are normally placed around the perimeter of the structure so that the air stream from each heater "wipes" the wall to produce a blanket of warm air along the building's outside walls where heat loss is greatest.

Standard Features

Low Installation Cost
Terminal blocks are supplied to facilitate connection of power supply and control wiring. Heaters are lightweight and usually require no special reinforcement to suspend them. Easy to install - just hang the heater, connect to power supply, controls and thermostat and it is ready to operate.

Dependability
Heating elements are resistant to thermal shock and vibration for a long, trouble-free life.

Application Flexibility
Equipped with adjustable horizontally positioned air deflector blades (HER units) to allow complete control over the air discharged by the unit.

Quiet Operation
Fans are accurately balanced to move air quietly. Motors mounted to fan guards utilize rubber vibration absorbing material for quieter operation.

Low Maintenance
Motors are totally enclosed, permanently lubricated, and thermally protected. Electrical contactors, fuses and transformers are all safety enclosed in control compartments.

Easy to Service
Fan and motor are exposed for easy removal without lowering the unit heater. Hinged bottom panel permits full access to controls.

Heater Warranty and Return Policy

It is the customer's responsibility to carefully inspect heaters for damage before accepting delivery since heaters are usually not returnable once delivery is accepted. Obviously damaged heaters should be refused and Greenhouse Megastore customer service contacted to make arrangements for a replacement unit. Once delivery is accepted Greenhouse Megastore will gladly provide replacement parts under the manufacturer's warranty to repair damaged or defective heaters; however this warranty does not include any labor costs associated with installing these parts. Warranty issues should be diagnosed by a certified HVAC technician since parts deemed not to be defective by the manufacturer are not available for credit back to the customer. Specific warranty policies vary by manufacturer but typically cover replacement parts as indicated above up to one year after purchase. Please contact Greenhouse Megastore customer service if you have any questions about the warranty for your specific heater.

Nice shirts for the price! But do not recommend for thick body types.
I bought 3 different ones. 2 Mediums and 1 2XL. The mediums fit correct and really nice! Would definitely recommend for the price! More like a exercise material, and sticks to your body shape... Sooo the 2Xl did not fit the person correct. Was so tight... And the strech is to stick to your body... So would not recommend for anyone a bit hefty or fit tbh. But the shirts are good materials and feel nice for a fresh day out or to use as gym clothes!!

Great Value heat gear material with high neck collar and loose fitting
Color: Black, Size: X-Large
My husband has been looking for mock neck shirts that are comparable to UA heat gear material but that are short sleeve and fit loose to wear under his work uniform. These seemed to have been a good soft quality option and the price is is great.

Favorite watch / solar
Color: Green/Green
I'm partial... I have bought Timex my intire life, they no doubt make the best watches... They take a licking, but keep on ticking is there old commercials.. True.. Great quality, keeps going after many year's... I never bought a solar watch from them prior I have to mention... It should hold up I'm thinking like their battery watches, I hope so. My favorite watch, I own a handful. Watch looks better in person... Downfall, they are trying a new band out of recycled plastic, I don't like it as much as the older bands it's soft, but feels a little strange...
